Determination of particle concentration in the breathing zone for four different types of office ventilation systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Many factors affect the airflow patterns, thermal comfort, contaminant removal efficiency and indoor air quality at individual workstations in office buildings. In this study, four ventilation systems were used in a test ...
Effects of different mechanical ventilation strategies on the mucociliary system
(SPRINGER, 2011)
To evaluate the effects of different mechanical ventilation (MV) strategies on the mucociliary system. Experimental study. Twenty-seven male New Zealand rabbits. After anesthesia, animals were tracheotomized and ventilated ...
Ammonia emissions in tunnel-ventilated broiler houses
(2011-10-01)
Gas production in broiler houses and their emissions are closely related to the microclimate established inside the house according to air temperature, humidity, and velocity. Therefore, the internal house environment is ...

Optimized ventilation model to improve operations in polymetallic mines in peru
(Springer Science and Business Media Deutschland GmbH, 2019-01-01)
Currently, deficient ventilation systems are a frequently observed problem in mining. Such deficient ventilation systems lead to the recirculation of stale air or air with toxic gases. This translates into an increase in ...
Bilevel vs ICU Ventilators Providing Noninvasive Ventilation: Effect of System Leaks A COPD Lung Model Comparison
(AMER COLL CHEST PHYSICIANS, 2009)
Background: Noninvasive positive-pressure ventilation (NPPV) modes are currently available on bilevel and ICU ventilators. However, little data comparing the performance of the NPPV modes on these ventilators are available. ...
